"but the fact its coming back midseason seems like a big mark against its quality. Am I right or am I right? Right?"
Wrong. Are you seriously suggesting that simply because a show starts mid-season, it's crap? There's undoubtedly a long list of shows that prove you wrong, but here's just a few:
Dallas, the original. The original Dallas was intended to be only a mid-season mini-series...but it went on for an additional 13 years!
Dallas, the new. A mid/late -season show, it was renewed for a second season after airing only 3 episodes. While it's hard to tell if it will enjoy the run of its predecessor, it's obviously not crap.
Stargate SG-1. A mid/late -season show. Lasted for 10 years.
Stargate Atlantis. Same as its' parent show, although it only lasted 5 years.
Flashpoint. A Canadian mid/late -season show picked up by CBS. Managed to last 5 years, despite CTV's (the Canadian network creating/airing it) best efforts to screw it up.
Babylon 5. A mid-season show that went on for 5 years.
I could go on, but I have other things to do today :-) Lets see what others come up with.
